Sauer's correspondence, and the manuscript and supporting documents for his unpublished "Methodists in Korea," make up the bulk of the collection. These materials document Methodist Episcopal mission work during Sauer's tenure in Korea, including the evacuation of missionary personnel in 1940, and their return in 1945. This was a critical transition phase for the Korean Methodist Church (KMC) as they struggled for power and control during the heightened Japanese control over churches in Korea, and then rebuilt after the war. There is also considerable material covering state of missions and the KMC during the invasion of South Korea in 1950. Photographs and publications nicely supplement this part of the collection.

The papers contains file folders on various places, organizations, and people Ralph T. Templin associated with during his missions. There are five files while he was at Central State University. Eight files directly related with missionary work in India but there are a number of others also pertaining to the India Missions. Eight files on the Puerto Rican independence nationalist movement which Ralph Templin strongly supported. There are various amounts on information pertaining to the Peacemaker movement and a number of files on personal correspondence. The other folders are manuscripts and published works. Some files contain photographs and newspaper clippings. The last box of the collection contains three large copies of Templin's, "Farewell Address" at Clancey High School. Two of the copies are in English and the final copy is in Sanskrit.
